Hey guys. I have a SBC 350, and 350 Auto trans. Holley carb #3310 (4160) carb. The car idles fine in park but falls on it's face when put in drive. The cam card is attached. I have checked for vaccum leakes and have adjusted the float level. I am stumped. When I set the the idle speed in park I am at about 1300 rpms then I put it in drive and it goes to 600-700 rpms or it dies. I do not know what else to check. I have played with the mixture screws and my timing is set at 12 BTDC. What am I overlooking? Thanks in advance.
